' SAFETY LID,

Application filed December 30, 1925. Serial No. 78,289; i

The present specification cpncerns a new lid or closure for allk1I1ClS-3f receptacles designed to contain liquids, pastes'or othersubstances in form of grains or powder.

lVitlithis new locking device, the maximum of economy is obtained, aswell as a perfect coupling; it has furthermore the great advantage thatit cannot be tampered with without leaving traces of such action, as itis absolutely necessary to mutilate the lid to be able to separate itfrom its seat.

For current use and if so desired, the receptacle can be covered with asupplementary capsule which protects the contents until consumed.

As will be seen further on, the invention is essentially consisting inthe formation of an annular groove at the mouth or orifice of thereceptacle or container into which is adjusted or fitted, by means of aconvenient mould, a stamped lid, with corrugations at the edge and whichpresents a central prominence, by means of which a surrounding lateralband is formed, which can be easily cut for withdrawing the lid, usingfor this purpose an instrument which will be delivered with thereceptacles, but which also can be substituted by any nail or similarpointed means. It is precisely this perforation which is the sign whichremains as an indication that the receptacle has been opened and whichas a metallic part is concerned, could only be concealed with greatdifficulty and still less erased, forming therefore an efficientguaranty, not only for the manufacturer, as it avoids that his goods canbe adulterated with impunity as happens with ordinary containers, butalso for the consumer as it is easy for him to know, at single sight,that the receptacle or container has been opened, which, as will beunderstood, is of great importance when liquids or articles foralimentary use are concerned.

For the better comprehension of this description, I add detaileddrawings in which:

Figure 1 shows in perspective a safety lid for receptacles orcontainers, constructed as per my invention, which is shown closed andwith instrument or opening lever in place.

Figure 2 is a level projection of the same locking device.

Figure 3 is a level projection of the capsule or lid, seen from above.

Figure 4 shows in elevation a vertical central cut-practised along theline as A-B of Figure Figure 5 shows in lateral elevation and as aconstructive variation a neck specially made to receive, besides the lidwith corrugations, a supplementary capsule which is shown in position.

Figure 6 shows the end of the neck with the groove and butts whichenables it to hold the supplementary capsule.

Figure 7 is a level projection of the mentioned capsule where the smalljuttings will be seen, which in combination with the groove hold it tothe neck.

In said drawings, 1 is the main part of the closing device which canform part of the material of the receptacle or container or, which alsocan be fixed to it in a way which will impede its being separated by thepublic. Said main part has as outlet an orifice into which a groove hasbeen made which will augment, at its extremity, the diameter of theorifice and into which the lid or capsule 2 will fit. Said groove showstwo characteristic points and these are: the interior elevation 3 whichis the point against which will operate as an hermetic coupling theraised conical part of the capsule and the annular outjutting nerve ofthe capsule, as soon as opened through the action of the mould withwhich it is fastened to the main part 1.

The lid or capsule 2 contains the corrugations 5 and an annular groove 6with which the central, raised, conical part is formed. It is preciselythe interior wall of bigger diameter than the groove 6 which adjusts toand closes hermetically the interior edge of the orifice of a minordiameter, formed in the main part 1.

As already mentioned, by means of a mould or other adequate means, thecapsule is fastened, compressing the part 6 until the corrugations 4approach against the interior part of the annular groove, formed by theedge or nerve of the main part 1. i

To extract the lid, an instrument 7 is used, as shown in Figure 1, oronly a nail or other pointed means which can be used as a lever againstthe edge of the orifice.

As a result of this, the lid 2 remains perforated and cannot be usedanew outside of the home, because it could not be used again as a coverfor the receptacle.

The whole closing device which has been described can be completed, ifdesired,

through the addition of a capsule 8 with interior juttings 9 which aredesigned to combine with the groove 10 of the neck.

This capsule is placed by pushing said juttings through the separations11 of the neck which are in combination with said groove and with thebutts 12.

It is logical that also any other common capsular system can be adapted.

Having now described and specified the nature of my invention and themanner in which it can be executed, what I claim as my exclusiveproperty and invention, is:

In a closure of the character described, the

combination with a receptacle mouth having a sealing chamber formed. byan annular groove, the outer portion thereof projecting under the lip ofthe mouth, of a sealing means for the chamber comprising a metal crownhaving its marginal portion bent downwardly at an angle to theperpendicular, then upwardly again to provide a recess for the elevatedportion of the groove and terminating in a corrugated outwardly projecting skirt portion insertable under the lip of said mouth, the entirecrown being disposed below the lip of the mouthwhen in closed position.
